Public folder to Shared mailbox Migration

Migrating public folders to Office 365 shared mailboxes is a strategic move for organizations to modernize communication and simplify management. Public folders, though effective for structured data sharing, can be complex to manage and scale. In contrast, shared mailboxes offer an efficient way to centralize emails, calendars, and tasks without requiring separate licenses or extensive administrative effort.

EdbMails Exchange Migration software makes this transition easy and secure. It simplifies the migration of public folders to Office 365 shared mailboxes, preserving data integrity, folder structure, and permissions. With EdbMails, you can reduce maintenance overhead, enhance collaboration, and ensure a hassle-free migration experience for improved team productivity.

EdbMails provides a reliable and efficient solution for organizations planning to migrate public folders to shared mailboxes in Office 365. It supports direct migration from on-premises Exchange servers, including Exchange 2019, 2016, 2013, and 2010, without the need for complex configurations or intermediate steps. EdbMails ensures a complete and accurate transfer of all public folder data, including emails, contacts, calendars, and folder hierarchy, while preserving permissions and metadata throughout the process.

With advanced filtering options, users can selectively migrate specific folders or items based on criteria such as date, subject, or item type, making the process more flexible and efficient. The software also supports incremental migration, which transfers only newly added or modified data during subsequent runs. This feature reduces bandwidth consumption, saves time, and prevents duplication of already migrated content, ensuring a consistent and optimized migration experience.
